Are you kidding me? GoT isn't available on HBO anywhere in my country, and I don't have the nerves to watch it on thos ad'full sites. Just DL from a torrent site, season by season. It's worth the time.

Make a 'Everything' folder' and just throw everything in there. There, organized. Jokes aside, I don't like having movies on my drive cause fragments, but you can easily delete episodes after watching them.
